Experiences with digital analysis of discharges in high voltage components

The ability of digital PD analyzers to process and store specific information concerning discharge activity can be used for various purposes: discharge recognition and condition monitoring. To exploit these possibilities, a specific fingerprint technique has been successfully used in recent years for off-line and on-line PD measurements of HV components. In this paper diverse practical examples are discussed of applying advanced digital post-processing for the measurement of partial discharges.
